. .Application inea June 15, 1921. serial No. 477,61?.

To a?? 1-7mm. z't may coiwern.:

Be it known that LFRANKG. KRAKAN, a citizenV of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new ing member constitutes a coiled Springwhich is housed for the purpose of excluding dust and dirt or other foreign substance.

Still another-object of the invention is to provide a device having rebound springs which act in conjunction with the main springs to prevent a too rapid return of the chassis to original position.

' Still another object 'of the invention resides in the provision o'f a device having longitudinal extending tie rods which provide fluides for the movable elements and prevent accidental lateral'displacement.

With these and other objects in v-iew the invention consists in the novel constructibn, combination and arrangement of parts which will be fully set forth in the followin, T specification` claimed and illustrated in the accompanying drawing, in which,

Figure l, is a side View of a portion of the forward end of a chassis sbowinfr my improved spring` in place, a portion thereof being in section to more clearly illustrate the details of construction,

Figure 2, is a. top plan view of the spring showing the upper link members removed and illustrating portions in sez-tion,

Figure 3, is a vertical sectional view taken on line 3-3 of Figure 1, and f Figure 4, is a plan view ot' one of the link members.

Referring to the drawings in detail, the numeral. 10 designates the chassis of the vehicle, the forward end of which is downturned as at 11 and is connected to the spring designated generically by the niimeral 12. y

This spring comprises telescopical sleeve members 13 and v14, the outer ends of which.

yare provided with plugs 15 which are formed on the inner sides of end lates 16.

An ear 17 extends lon 'tudinaly from the outer side'of each p ate 16 which is pierced to receive al bolt 18,'Yby means of which the spring is secured to the chassis. Each plate 16 is provided adjacent its outer ends, with-openings to receive the tie rods v19 which act as guides for the crossheads which will be more fully hereinafter described. i f

-Fittedqinto the inner end of eachtelescopi'c memberk 14 is a plugl 20 which is formed integral with a cross head 21, having openings 22 therein for the reception of the guide rod 19. Extending upwardly and downwardly from each cross head intermediate its end, are ears 23 and 24 respectively, to provide connections for the link members which will be more fully hereinafter described.

The link members above referred'to designated generically by `the numeral 25v and each comprises a. bifurcated head 26 which is pierced to receive bolts` 27 b means of which the links are' connected wit the ears 23 and 24. -The opposite end of each link is provided with av head 28, hav' ingextending longitudinally therefrom an ear 29 which is pierced to receive a bolt 30 by means otuwhich the adjacent ends -o. the links are' connected to, the vertically fmovable plates 31 which in turn are secured to the chassis and to the axle of the vehicle, as will be clearly understood by reference to Fi re 1.

In order tohold the,device in proper position and provide the desired resilience, suitable compression coil springs 32 are arranged in the telescopic sleeves|13 and 14 and surround a guide rod 33, theVV outer end of which is received yin the plug 15, while the-,inner end is secured to a. cross member are..

34 Iwhich is rigidly fixed on the guide rods,k

19 at a point intermediate their ends.

The cross member 34 above referred tu, forms the abutment for the inner end of each rebound spring 35 which is contained within telescopic tubular. housings 36 W ich are arranged between/the cross heads 21 and the cross member 34, as will be clearly seen from reference to the drawings. f Q

lin operation it will be seen that when an' obstruction i's encountered in the roadand` the vehiclel axle is driven upwardly, the

' return of the axle to normal position under theI influence of the springs 32, it will be obvioiis that rebound shocks, will be absorbed by the springs 35 and in this inanner riding comfort will be. .greatly lenhanced. @wing to the complete housing of all ot the springs, it will be obvious that it so desired they may be packed with lubricant and foreign substances will he excluded.I therebjir increasing; the length of life, of the springs and protecting the saine from injury.

lllliiile in the. Jforegoing there has been shown and described the preferred embodiment of this invention. it is to be understood that certain Ininor changes. in the details or" construction. combination and arrangement of parts may be resorted to without departing from the spirit und scope of the invention as claimed.

l/Vhat is claimed is 1* l. A vehicle spring comprising guide rods fixed at their ends to a vehicle, traine. springs exending longitudinally with relation to the `enide rods, and a link inerhzniism slidable on said guide rods between :uliacent ends of the springs, said link mechanism intervening between the traine and the axle of the vehicle.

2. 1vehicle spring comprising guide rods fixed at their ends to s vehicle treme. springs extending longitudinally,with relation to the guide rods, s linkniechanisin slidable on said guide rods between adjacent ends ol" the springs, said link mechanism intervening hetn'een the traine and the sxle of the vehicle, and rebound springs associated with the link mechanism.

3. A vchicle spring comprising guide rods fixed at their ends to a vehicle frame, springs extending longitudinally with relation to the guide rods, a link mechanism slidahle on said guide rods between adjacent ends of the springs, said link mechanism intervening between the Jlrarne and the axle of the vehicle, and telescopic housings inolosing said springs. 1

A vehicle spring comprising guide rods Menem fixed at their ends to a vehicle freine, springs extending longitudinally with relation to the guide rods. a link mechanism slidable on said guide rods between adjacent ends ol" the springs.l said link mechanismintervening between frame and the axle or' the Vehicle und rebound springs associated with the link mechanism, and telescopic housings inelosing said springs.

A vehicle spring comprising. spaced parallel guide rods Fixed at their ends to a vehicle frame, springs extending longitudinally between the rods. the outer ends ol the springs being fixed. a link mechanism slidable on the guide rods and abutting adjacent ends of the springs, the upper and lower ends of the 'link mechanisrnbeing attached to a rehiole chassis and axle respectirelfyf, rebound springs associated with the link mech anisln, and guide rods extending through the springs.

6. A vehicle spring comprising, spaced parallel guide rods fixed at their ends to a vehicle trame, springs extending longitudinally between the rods, the outer ends of the springs being fixed, a link mechanism s|id able on the guide rods find abutting 'adjacent ends of the springs, the upper and lower ends of the link mechanism being` attached to' a vehicle chassis and axle respectively, rebound springs associated with the link 'niechanisrm and guide rods extending through the springs, and telescopic housings inelosing said springs.

7. vehicle spring comprising, n pair of fixed end plates, parallel spaced guide rods4 holding said plates in spaced relation, corn` pression coiled springsl abutting the inner sides of said plates, -erossheeds slidzible on the guide rods and abutting the inner ends ol the springs, and a link 'mechanism connected to the crossheads and disposed between' the, vehicle chassis and erle and adapted to suport the weight oli the vehicle.
